This section describes procedures used to set up a \*(4B UNIX system.

|
These procedures are used when a system is first installed
|
|
or when the system configuration changes. Procedures for normal

.Sh 2 "Kernel configuration"
|

how files for devices are made.

|
and building system images, consult the document ``Building

|
4.3BSD UNIX Systems with Config'' (SMM:2).
|
|
.Sh 3 "Kernel organization"
|
|
.PP
|
|
As distributed, the kernel source is in a
|
|
separate tar image. The source may be physically
|
|
located anywhere within any filesystem so long as
|
|
a symbolic link to the location is created for the file
|
|
.Pn /sys
|
|
(many files in
|
|
.Pn /usr/include
|
|
are normally symbolic links relative to
|
|
.Pn /sys ).
|
|
In further discussions of the system source all path names
|
|
will be given relative to
|
|
.Pn /sys .

.Sh 3 "Devices and device drivers"
|
|
.PP
|
|
Devices supported by UNIX are implemented in the kernel
|
|
by drivers whose source is kept in
|
|
.Pn /sys/<architecture>/dev .
|
|
These drivers are loaded
|
|
into the system when included in a CPU specific configuration file
|
|
kept in the conf directory. Devices are accessed through special
|
|
files in the filesystem, made by the
|
|
.Xr mknod (8)
|
|
program and normally kept in the
|
|
.Pn /dev
|
|
directory.
|
|
For all the devices supported by the distribution system, the
|
|
files in
|
|
.Pn /dev
|
|
are created by the
|
|
.Pn /dev/MAKEDEV
|
|
shell script.
|
|
.PP
|
|
Determine the set of devices that you have and create a new
|
|
.Pn /dev
|
|
directory by running the MAKEDEV script.
|
|
First create a new directory
|
|
.Pn /newdev ,
|
|
copy MAKEDEV into it, edit the file MAKEDEV.local
|
|
to provide an entry for local needs,
|
|
and run it to generate a
|
|
.Pn /newdev directory.
|
|
For instance,
|
|
.DS
|
|
\fB#\fP \fIcd /\fP
|
|
\fB#\fP \fImkdir newdev\fP
|
|
\fB#\fP \fIcp dev/MAKEDEV newdev/MAKEDEV\fP
|
|
\fB#\fP \fIcd newdev\fP
|
|
\fB#\fP \fIMAKEDEV \*(Dk0 pt0 std LOCAL\fP
|
|
.DE
|
|
Note the ``std'' argument causes standard devices such as
|
|
.Pn /dev/console ,
|
|
the machine console, to be created.
|
|
.PP
|
|
You can then do
|
|
.DS
|
|
\fB#\fP \fIcd /\fP
|
|
\fB#\fP \fImv dev olddev ; mv newdev dev\fP
|
|
\fB#\fP \fIsync\fP
|
|
.DE
|
|
to install the new device directory.
|
|
.Sh 3 "Building new system images"
|
|
.PP
|
|
The kernel configuration of each UNIX system is described by
|
|
a single configuration file, stored in the
|
|
.Pn /sys/<architecture>/conf
|
|
directory.
|
|
To learn about the format of this file and the procedure used
|
|
to build system images,
|
|
start by reading ``Building 4.3BSD UNIX Systems with Config'' (SMM:2),
|
|
look at the manual pages in section 4
|
|
of the UNIX manual for the devices you have,
|
|
and look at the sample configuration files in the
|
|
.Pn /sys/<architecture>/conf
|
|
directory.
|
|
.PP
|
|
The configured system image
|
|
.Pn vmunix
|
|
should be copied to the root, and then booted to try it out.
|
|
It is best to name it
|
|
.Pn /newvmunix
|
|
so as not to destroy the working system until you are sure it does work:
|
|
.DS
|
|
\fB#\fP \fIcp vmunix /newvmunix\fP
|
|
\fB#\fP \fIsync\fP
|
|
.DE
|
|
It is also a good idea to keep the previous system around under some other
|
|
name. In particular, we recommend that you save the generic distribution
|
|
version of the system permanently as
|
|
.Pn /genvmunix
|
|
for use in emergencies.
|
|
To boot the new version of the system you should follow the
|
|
bootstrap procedures outlined in section 6.1.
|
|
After having booted and tested the new system, it should be installed as
|
|
.Pn /vmunix
|
|
before going into multiuser operation.
|
|
A systematic scheme for numbering and saving old versions
|
|
of the system may be useful.
|
|
.Sh 2 "Configuring terminals"
|
|
.PP
|
|
If UNIX is to support simultaneous
|
|
access from directly-connected terminals other than the console,
|
|
the file
|
|
.Pn /etc/ttys
|
|
(see
|
|
.Xr ttys (5))
|
|
must be edited.
|
|
.PP
|
|
To add a new terminal device, be sure the device is configured into the system
|
|
and that the special files for the device have been made by
|
|
.Pn /dev/MAKEDEV .
|
|
Then, enable the appropriate lines of
|
|
.Pn /etc/ttys
|
|
by setting the ``status''
|
|
field to \fBon\fP (or add new lines).
|
|
Note that lines in
|
|
.Pn /etc/ttys
|
|
are one-for-one with entries in the file of current users
|
|
(see
|
|
.Pn /var/run/utmp ),
|
|
and therefore it is best to make changes
|
|
while running in single-user mode
|
|
and to add all the entries for a new device at once.
|
|
.PP
|
|
Each line in the
|
|
.Pn /etc/ttys
|
|
file is broken into four tab separated
|
|
fields (comments are shown by a `#' character and extend to
|
|
the end of the line). For each terminal line the four fields
|
|
are:
|
|
the device (without a leading
|
|
.Pn /dev ),
|
|
the program
|
|
.Pn /sbin/init
|
|
should startup to service the line
|
|
(or \fBnone\fP if the line is to be left alone),
|
|
the terminal type (found in
|
|
.Pn /usr/share/misc/termcap ),
|
|
and optional status information describing if the terminal is
|
|
enabled or not and if it is ``secure'' (i.e. the super user should
|
|
be allowed to login on the line).
|
|
If the console is marked as ``insecure'',
|
|
then the root password is required to bring the machine up single-user.
|
|
All fields are character strings
|
|
with entries requiring embedded white space enclosed in double
|
|
quotes.
|
|
Thus a newly added terminal
|
|
.Pn /dev/tty00
|
|
could be added as
|
|
.DS
|
|
tty00 "/usr/libexec/getty std.9600" vt100 on secure # mike's office
|
|
.DE
|
|
The std.9600 parameter provided to
|
|
.Pn /usr/libexec/getty
|
|
is used in searching the file
|
|
.Pn /etc/gettytab ;
|
|
it specifies a terminal's characteristics (such as baud rate).
|
|
To make custom terminal types, consult
|
|
.Xr gettytab (5)
|
|
before modifying
|
|
.Pn /etc/gettytab .
|
|
.PP
|
|
Dialup terminals should be wired so that carrier is asserted only when the
|
|
phone line is dialed up.
|
|
For non-dialup terminals, from which modem control is not available,
|
|
you must wire back the signals so that
|
|
the carrier appears to always be present. For further details,
|
|
find your terminal driver in section 4 of the manual.
|
|
.PP
|
|
For network terminals (i.e. pseudo terminals), no program should
|
|
be started up on the lines. Thus, the normal entry in
|
|
.Pn /etc/ttys
|
|
would look like
|
|
.DS
|
|
ttyp0 none network
|
|
.DE
|
|
(Note, the fourth field is not needed here.)
|
|
.PP
|
|
When the system is running multi-user, all terminals that are listed in
|
|
.Pn /etc/ttys
|
|
as \fBon\fP have their line enabled.
|
|
If, during normal operations, you wish
|
|
to disable a terminal line, you can edit the file
|
|
.Pn /etc/ttys
|
|
to change the terminal's status to \fBoff\fP and
|
|
then send a hangup signal to the
|
|
.Xr init
|
|
process, by doing
|
|
.DS
|
|
\fB#\fP \fIkill \-s HUP 1\fP
|
|
.DE
|
|
Terminals can similarly be enabled by changing the status field
|
|
from \fBoff\fP to \fBon\fP and sending a hangup signal to
|
|
.Xr init .
|
|
.PP
|
|
Note that if a special file is inaccessible when
|
|
.Xr init
|
|
tries to create a process for it,
|
|
.Xr init
|
|
will log a message to the
|
|
system error logging process (see
|
|
.Xr syslogd (8))
|
|
and try to reopen the terminal every minute, reprinting the warning
|
|
message every 10 minutes. Messages of this sort are normally
|
|
printed on the console, though other actions may occur depending
|
|
on the configuration information found in
|
|
.Pn /etc/syslog.conf .
|
|
.PP
|
|
Finally note that you should change the names of any dialup
|
|
terminals to ttyd?
|
|
where ? is in [0-9a-zA-Z], as some programs use this property of the
|
|
names to determine if a terminal is a dialup.
|
|
Shell commands to do this should be put in the
|
|
.Pn /dev/MAKEDEV.local
|
|
script.
|
|
.PP
|
|
While it is possible to use truly arbitrary strings for terminal names,
|
|
the accounting and noticeably the
|
|
.Xr ps (1)
|
|
command make good use of the convention that tty names
|
|
(by default, and also after dialups are named as suggested above)
|
|
are distinct in the last 2 characters.
|
|
Change this and you may be sorry later, as the heuristic
|
|
.Xr ps (1)
|
|
uses based on these conventions will then break down and
|
|
.Xr ps
|
|
will run MUCH slower.
|
|
.Sh 2 "Adding users"
|
|
.PP
|
|
The procedure for adding a new user is described in
|
|
.Xr adduser (8).
|
|
You should add accounts for the initial user community, giving
|
|
each a directory and a password, and putting users who will wish
|
|
to share software in the same groups.
|
|
.PP
|
|
Several guest accounts have been provided on the distribution
|
|
system; these accounts are for people at Berkeley,
|
|
Bell Laboratories, and others
|
|
who have done major work on UNIX in the past. You can delete these accounts,
|
|
or leave them on the system if you expect that these people would have
|
|
occasion to login as guests on your system.
|
|
.Sh 2 "Site tailoring"
|
|
.PP
|
|
All programs that require the site's name, or some similar
|
|
characteristic, obtain the information through system calls
|
|
or from files located in
|
|
.Pn /etc .
|
|
Aside from parts of the
|
|
system related to the network, to tailor the system to your
|
|
site you must simply select a site name, then edit the file
|
|
.DS
|
|
/etc/netstart
|
|
.DE
|
|
The first lines in
|
|
.Pn /etc/netstart
|
|
use a variable to set the hostname,
|
|
.DS
|
|
hostname=\fImysitename\fP
|
|
/bin/hostname $hostname
|
|
.DE
|
|
to define the value returned by the
|
|
.Xr gethostname (2)
|
|
system call. If you are running the name server, your site
|
|
name should be your fully qualified domain name. Programs such as
|
|
.Xr getty (8),
|
|
.Xr mail (1),
|
|
.Xr wall (1),
|
|
and
|
|
.Xr uucp (1)
|
|
use this system call so that the binary images are site
|
|
independent.
|
|
.PP
|
|
You will also need to edit
|
|
.Pn /etc/netstart
|
|
to do the network interface initialization using
|
|
.Xr ifconfig (8).
|
|
If you are not sure how to do this, see sections 5.1, 5.2, and 5.3.
|
|
If you are not running a routing daemon and have
|
|
more than one Ethernet in your environment
|
|
you will need to set up a default route;
|
|
see section 5.4 for details.
|
|
Before bringing your system up multiuser,
|
|
you should ensure that the networking is properly configured.
|
|
The network is started by running
|
|
.Pn /etc/netstart .
|
|
Once started, you should test connectivity using
|
|
.Xr ping (8).
|
|
You should first test connectivity to yourself,
|
|
then another host on your Ethernet,
|
|
and finally a host on another Ethernet.
|
|
The
|
|
.Xr netstat (8)
|
|
program can be used to inspect and debug
|
|
your routes; see section 5.4.
|
|
.Sh 2 "Setting up the line printer system"
|
|
.PP
|
|
The line printer system consists of at least
|
|
the following files and commands:
|
|
.DS
|
|
.TS
|
|
l l.
|
|
/usr/bin/lpq spooling queue examination program
|
|
/usr/bin/lprm program to delete jobs from a queue
|
|
/usr/bin/lpr program to enter a job in a printer queue
|
|
/etc/printcap printer configuration and capability database
|
|
/usr/sbin/lpd line printer daemon, scans spooling queues
|
|
/usr/sbin/lpc line printer control program
|
|
/etc/hosts.lpd list of host allowed to use the printers
|
|
.TE
|
|
.DE
|
|
.PP
|
|
The file
|
|
.Pn /etc/printcap
|
|
is a master database describing line
|
|
printers directly attached to a machine and, also, printers
|
|
accessible across a network. The manual page
|
|
.Xr printcap (5)
|
|
describes the format of this database and also
|
|
shows the default values for such things as the directory
|
|
in which spooling is performed. The line printer system handles
|
|
multiple printers, multiple spooling queues, local and remote
|
|
printers, and also printers attached via serial lines that require
|
|
line initialization such as the baud rate. Raster output devices
|
|
such as a Varian or Versatec, and laser printers such as an Imagen,
|
|
are also supported by the line printer system.
|
|
.PP
|
|
Remote spooling via the network is handled with two spooling
|
|
queues, one on the local machine and one on the remote machine.
|
|
When a remote printer job is started with
|
|
.Xr lpr ,
|
|
the job is queued locally and a daemon process created to oversee the
|
|
transfer of the job to the remote machine. If the destination
|
|
machine is unreachable, the job will remain queued until it is
|
|
possible to transfer the files to the spooling queue on the
|
|
remote machine. The
|
|
.Xr lpq
|
|
program shows the contents of spool
|
|
queues on both the local and remote machines.
|
|
.PP
|
|
To configure your line printers, consult the printcap manual page
|
|
and the accompanying document, ``4.3BSD Line Printer Spooler Manual'' (SMM:7).
|
|
A call to the
|
|
.Xr lpd
|
|
program should be present in
|
|
.Pn /etc/rc .
|
|
.Sh 2 "Setting up the mail system"
|
|
.PP
|
|
The mail system consists of the following commands:
|
|
.DS
|
|
.TS
|
|
l l.
|
|
/usr/bin/mail UCB mail program, described in \fImail\fP\|(1)
|
|
/usr/sbin/sendmail mail routing program
|
|
/var/spool/mail mail spooling directory
|
|
/etc/aliases mail forwarding information
|
|
/usr/bin/newaliases command to rebuild binary forwarding database
|
|
/usr/bin/biff mail notification enabler
|
|
/usr/libexec/comsat mail notification daemon
|
|
.TE
|
|
.DE
|
|
Mail is normally sent and received using the
|
|
.Xr mail (1)
|
|
command (found in
|
|
.Pn /usr/bin/mail ),
|
|
which provides a front-end to edit the messages sent
|
|
and received, and passes the messages to
|
|
.Xr sendmail (8)
|
|
for routing.
|
|
The routing algorithm uses knowledge of the network name syntax,
|
|
aliasing and forwarding information, and network topology, as
|
|
defined in the configuration file
|
|
.Pn /usr/lib/sendmail.cf ,
|
|
to process each piece of mail.
|
|
Local mail is delivered by giving it to the program
|
|
.Pn /usr/libexec/mail.local
|
|
that adds it to the mailboxes in the directory
|
|
.Pn /var/spool/mail/<username> ,

using a locking protocol to avoid problems with simultaneous updates.
|
|
After the mail is delivered, the local mail delivery daemon
|
|
.Pn /usr/libexec/comsat
|
|
is notified, which in turn notifies users who have issued a
|
|
``\fIbiff\fP y'' command that mail has arrived.
|
|
.PP
|
|
Mail queued in the directory
|
|
.Pn /var/spool/mail
|
|
is normally readable only by the recipient.
|
|
.PP
|
|
To set up the mail facility you should read the instructions in the
|
|
file READ_ME in the directory
|
|
.Pn /usr/src/usr.sbin/sendmail
|
|
and then adjust the necessary configuration files.
|
|
You should also set up the file
|
|
.Pn /etc/aliases
|
|
for your installation, creating mail groups as appropriate.

This section gives a brief overview of
|
|
.Xr uucp
|
|
and points out the most important steps in its installation.
|
|
.PP
|
|
To connect two UNIX machines with a
|
|
.Xr uucp
|
|
network link using modems,
|
|
one site must have an automatic call unit
|
|
and the other must have a dialup port.
|
|
It is better if both sites have both.
|
|
.PP
|
|
You should first read the paper in the UNIX System Manager's Manual:
|
|
``Uucp Implementation Description'' (SMM:14).
|
|
It describes in detail the file formats and conventions,
|
|
and will give you a little context.
|
|
In addition,
|
|
the document ``setup.tblms'',
|
|
located in the directory
|
|
.Pn /usr/src/usr.bin/uucp/UUAIDS ,
|
|
may be of use in tailoring the software to your needs.
|
|
.PP
|
|
The
|
|
.Xr uucp
|
|
support is located in three major directories:
|
|
.Pn /usr/bin,
|
|
.Pn /usr/lib/uucp,
|
|
and
|
|
.Pn /var/spool/uucp .
|
|
User commands are kept in
|
|
.Pn /usr/bin,
|
|
operational commands in
|
|
.Pn /usr/lib/uucp ,
|
|
and
|
|
.Pn /var/spool/uucp
|
|
is used as a spooling area.
|
|
The commands in
|
|
.Pn /usr/bin
|
|
are:
|
|
.DS
|
|
.TS
|
|
l l.
|
|
/usr/bin/uucp file-copy command
|

|
|
/usr/bin/uuencode binary file encoder (for \fIuusend\fP)
|
|
/usr/bin/uudecode binary file decoder (for \fIuusend\fP)
|
|
/usr/bin/uulog scans session log files
|
|
/usr/bin/uusnap gives a snap-shot of \fIuucp\fP activity
|
|
/usr/bin/uupoll polls remote system until an answer is received
|
|
/usr/bin/uuname prints a list of known uucp hosts
|

To install
|
|
.Xr uucp
|
|
on your system,
|
|
start by selecting a site name
|
|
(shorter than 14 characters).
|
|
A
|
|
.Xr uucp
|
|
account must be created in the password file and a password set up.
|
|
Then,
|
|
create the appropriate spooling directories with mode 755
|
|
and owned by user
|
|
.Xr uucp ,
|
|
group \fIdaemon\fP.
|
|
.PP
|
|
If you have an auto-call unit,
|
|
the L.sys, L-dialcodes, and L-devices files should be created.
|
|
The L.sys file should contain
|
|
the phone numbers and login sequences
|
|
required to establish a connection with a
|
|
.Xr uucp
|
|
daemon on another machine.
|
|
For example, our L.sys file looks something like:
|
|
.DS
|
|
adiron Any ACU 1200 out0123456789- ogin-EOT-ogin uucp
|
|
cbosg Never Slave 300
|
|
cbosgd Never Slave 300
|
|
chico Never Slave 1200 out2010123456
|
|
.DE
|
|
The first field is the name of a site,
|
|
the second shows when the machine may be called,
|
|
the third field specifies how the host is connected
|
|
(through an ACU, a hard-wired line, etc.),
|
|
then comes the phone number to use in connecting through an auto-call unit,
|
|
and finally a login sequence.
|
|
The phone number
|
|
may contain common abbreviations that are defined in the L-dialcodes file.
|
|
The device specification should refer to devices
|
|
specified in the L-devices file.
|
|
Listing only ACU causes the
|
|
.Xr uucp
|
|
daemon,
|
|
.Xr uucico ,
|
|
to search for any available auto-call unit in L-devices.
|
|
Our L-dialcodes file is of the form:
|
|
.DS
|
|
ucb 2
|
|
out 9%
|
|
.DE
|
|
while our L-devices file is:
|
|
.DS
|
|
ACU cul0 unused 1200 ventel
|
|
.DE
|
|
Refer to the README file in the
|
|
.Xr uucp
|
|
source directory for more information about installation.
|
|
.PP
|
|
As
|
|
.Xr uucp
|
|
operates it creates (and removes) many small
|
|
files in the directories underneath
|
|
.Pn /var/spool/uucp .
|
|
Sometimes files are left undeleted;
|
|
these are most easily purged with the
|
|
.Xr uuclean
|
|
program.
|
|
The log files can grow without bound unless trimmed back;
|
|
.Xr uulog
|
|
maintains these files.
|
|
Many useful aids in maintaining your
|
|
.Xr uucp
|
|
installation are included in a subdirectory UUAIDS beneath
|
|
.Pn /usr/src/usr.bin/uucp .
|
|
Peruse this directory and read the ``setup'' instructions also located there.
